Celo considering transition to Ethereum layer-2 with Polygon Chain

Celo, a blockchain platform, is exploring migrating from its standalone blockchain to the Ethereum (ETH) layer-2 (L2) network. Originally, Celo planned to use Optimism’s OP Stack, a customizable toolkit similar to Polygon (MATIC) but based on Optimism’s technology.

However, Polygon Labs co-founder Sandeep Nailwal has proposed an alternative solution to the Celo community. Nailwal suggests leveraging Polygon’s Chain Development Kit (CDK), an open-source toolset that enables the creation of customizable layer-2 chains powered by zero-knowledge (ZK) technology.

Possible migration of Celo to Ethereum Layer-2 via Polygon

In a recent blog post, Polygon Labs suggested that Celo could consider deploying an Ethereum layer-2 solution using the Polygon CDK.

According to Polygon Labs co-founder Nailwal, this strategy will allow Celo to take advantage of the benefits of being an Ethereum layer-2 platform while preserving the features that have contributed to its success.

The proposal highlights several key benefits of adopting the Polygon CDK. First, it enables cross-community collaboration by integrating with an ecosystem of layer-2 solutions powered by zero-knowledge technology.

The Polygon CDK extends compatibility with Ethereum by providing an environment equivalent to the Ethereum Virtual Machine (EVM). This alignment ensures a seamless transition to Celo, which closely matches Ethereum’s technical infrastructure and tooling.

Additionally, according to Nailwal, the protocol’s deployment with its CDK provides enhanced security for Celo. This allows Celo to leverage Ethereum’s proven consensus layer while incorporating the security benefits of zero-knowledge proofs.

Regarding fees and scalability, Celo can benefit from lower fees by using the zkEVM Validium architecture and off-chain data availability supported by the Polygon CDK. These features contribute to cost-efficient transactions while enabling scalability for Celo’s network.

Additionally, according to Nailwal, Celo gains access to the integrated layer-2 economy by becoming part of the Polygon ecosystem by connecting Ethereum’s mainnet with Polygon’s ecosystem. This integration creates a seamless experience for developers and users, facilitating interaction with both networks.

Faster transactions and lower fees?

With zero-knowledge technology, Celo users can enjoy near-instant withdrawals, fast closing times, and instant cross-chain interactivity.

According to the blog post, these features increase the speed, efficiency, and security of transactions, which ultimately improves the user experience.

Through the Polygon CDK, chains can achieve near-instantaneous cross-chain interoperability with Ethereum, leveraging the power of ZK Proof to establish a secure and interconnected network.

Overall, the proposed migration to the Polygon CDK represents an opportunity for Celo to transition to an Ethereum layer-2 solution while utilizing the advantages offered by Polygon’s ZK-powered technology. The purpose of the proposal is to initiate discussions between the Celo and Polygon communities to explore the potential benefits for all stakeholders involved.

It is important to note that no final decisions have been made at this stage, and the proposal marks the beginning of discussion between the Celo and Polygon communities.
